WEDNESDAY, DEC. 10 TH

104 12/10/14 Wed. L.T.: I can practice using the speed equation to find the speed of various moving objects. DO NOW: On most freeways, you’re supposed to go 60 mph (miles per hour). What does that really mean in terms of your car’s motion? ………………… Reflection: What definition or explanation would you give for speed? Use your understanding from the reading yesterday, our DO NOW, and our activity today to back up WHY that is your definition. 105 Title: Need for Speed 1: tuna 2: cheetah 3: kangaroo 4: Earth’s spin 5: snail 6: slug 7: fastball 8: satellites 9: Formula Rossi 10: Lockhead 11: McLaren Rankings:
